Motion,Space and time are the arena in which all physical events take place. An object’s position in space will generally change with time; this obvious phenomenon, ., is used as our first clue for deducing the laws of physics. The study of motion is traditionally called ..

SLAG

Force,What causes anything to move as it does? This is one of the most fundamental questions of physics, and the science of . has been developed to deal with it; this chapter is an introduction to that subject. In this area our thinking has been shaped almost entirely by one man, Sir Isaac Newton (1642–1727).

Energy,Energy, like force and motion, is an unspecialized concept, applicable to almost all fields of physics, and providing them with a common unit of measurement. Energy plays a starring role in the most abstract theories as well as in the most practical concerns. Everyone, of course, is aware of its economic, social, and military importance.

Circular Motion,The circle is surely among the simplest of curves. Nevertheless, a particle in circular orbit necessarily experiences forces and accelerations that are far from trivial.

Heat,This chapter introduces two concepts: . and .. Both phenomena have always played a prominent role in man’s daily life, everyone has a good intuitive grasp of them, and they are quite easy to measure. Yet they have been surprisingly slow in reaching precise quantitative status. (This happened, roughly, between 1800 and 1850.)

Molecules and Gases,This chapter is our first bridge between the study of ordinary objects and that of their microscopic constituents, the molecules. It is organized as follows.

Electric Charge and Its Field,We are now reaching an important milestone—the beginning of electrical science. In these pages, the subject will be developed, as it was historically, from an initial study of .; this forms the topic of .. (Moving charges exhibit an additional range of phenomena, ., about which more later.)
